In November 2017 our flame retardant fabric Volcano has been successfully retested and renewed EN 1149-5 (Protective clothing. Electrostatic properties) certificate.
EN 1149-5 is European standard for garments that protect against electrostatic discharge where there is a risk of explosion e.g. in oil refineries.
It is part of a series of standards for test methods and requirements for electrostatic properties of protective clothing.
EN 1143-3 is a test method, that uses induction charging to evaluate how fast a fabric discharge, i.e. looses its electrostatic charge via air. According to the Standard the charge decay value should be no more than 4 seconds according to test method EN 1149-3. It means that antistatic fabric should loose its electrostatic charge in less than 4s.
Volcano is an innovative flame retardant fabric made of cotton-nylon blend, which is extremely tear-resistant and durable. This durability lets sufficiently increased life circle of flame retardant clothing. This FR fabric is also certified to ISO 11612 and ISO 11611 standards for protective clothing. Moreover, Volcano has additional Multi-risk treatment, which adds protection against acids, oil, grease and water.
Volcano has been successfully tested to the following test:
Charge decay, according EN 1149-3:2004 (after 5 washing cycles at 400C, ISO 6330:2012, Tumble Dry, F). – performance level – PASS
According to Standard EN 1149-5:2008 for the induction charge method (EN 1149-3:2004) the requirements are:
t50< 4 s or S > 0,2
During the testing, Volcano has demonstrated the following results:
- S = 0,78 – Shielding factor – PASS
- t50 = < 0,01 – Decay half time – PASS
It means that when tested, Volcano fabric dissipated (lost) its electrostatic charge in less than 0,01 second. So it’s 400 times better, than EN 1149-5 requirements.
